This invention relates to the class of ship supplies and moreparticularly to a device for use in. connection with the dischargeoutlets for cool ing water, waste and the like which extend through theskin of a ship.

In the construction of ships it is necessary to place outlets throughthe skin of the ships and on each side thereof. These outlets carry offcooling water from the engines and generators, waste from the sanitarysystem, and the fluids that are pumped from the holes and bilges. Whenships are alongside docks or piers, unlessthese holes are covered thewater is projected onto the dock. Likewise, in the case of a ship atanchor such discharge will be projected out onto the decks of smallboats that may be brought alongside the ship. In most countries thereare strict laws enforced whereby these discharge outlets must be coveredin such a way that the water falls harmlessly down the side of a shipand not onto the dock. Accordingly, most ships carry some form of chute,and the former art devices consist of different types of chutes whichare constructed of wood with lead weights attached,

to the bottom to withstand the pressure of wvater. Others consist of acanvas bag with pockets in the lower ends which, when filled with waterbecome self-weighting. However, each of these forms of discharge chutesare quite unsatisfactory since they are both bulky and diflicult tohandle, difficult to position over the discharge outlet due to theoverhang of the main deck over that portion of the hole through whichthe discharge outlet extends, and because the prior art chutes permitflow of water or other fluids in an improper manner due to the improperengagement between the chute and the skin of the ship. Therefore, it isa further object of this invention to provide magnetic means for urginga chute into engagement with the skin of a ship. A further object ofthis invention is to provide novel means for securing a magnetic memberin a casing of a chute so as to be sufficiently waterproof so as toafford proper operation thereof.

Still another object of this invention resides in the provision of novelmeans for suspending a casing forming an overboard discharge chute whichsuspension means includes means for transmission of current to magneticmeans urging the casing into engagement with the skin of a ship.

Still further objects or the invention reside in the provision of anoverboard discharge chute that is strong, durable, highly efficient inoper- 2 Claims. (01. 114-221) wherein:

These, together with the various ancillary objects of the inventionwhich will become apparent as the following description proceeds, areattained by this overboard discharge chute, a preferred embodiment ofwhich has been illustrated in the accompanying drawings, by way ofexample,

"Figure 1 is a perspective view of the overboard discharge chute shownin operative relation against the hole of a ship;

Figure 2 is an enlarged vertical sectional view as taken along line 2-2in Figure 1;

Figure 3 is an enlarged horizontal sectional view as taken along line3-3 in Figure 2;

Figure 4 is an enlarged sectional detail as taken along line 4-4 inFigure 3;

Figure 5 is a detail view showing the construction of the members usedin supporting the casing.

With continuing reference to the accompanying drawings wherein likereference numerals designate similar parts throughout the various views,reference numeral ill generally designates the hull of a ship which isformed from heel plates which are welded or riveted together to thusform a magnetic skin. Extending through this skin are discharge outlets12 through which cooling water from the engines or generators of a shipor the waste may flow. To prevent this waste from splashing onto a smallboat which may be borne alongside the ship or to splash onto a dock orpier there is provided the overboard discharge chute which includes acasing l4 having a front wall I6, side walls l8 and a top wall 20. Thecasing 14 is open at the rear and at the bottom thereof and the casingmay be of any desired configuration so as to conform with the contoursof the ship's hull. Extending through the casing and more particularlythrough the front wall [6 thereof is a U-shaped iron core member 22which is provided with a pair of parallel legs 24 and.26. Received onthe legs 24 and 26 are coils 28 which are encased within a suitablehousing 30. The coils are waterproofed by any convenient means and areelectrically operatively. conducted to a source of electrical power onthe ship.

For supporting the casing I4 at the desired location there is providedL-shaped hook members 32 which embrace the casing 30 of the coils andwhich extend up to form an arcuate eye portion 34 through which cables36 are secured.

The cables 36 are secured to a junction member 38 which junction memberis supported by a flexible rubber covered line 40 having a strengthmember 42 forming the core thereof about which conductors 44 arewrapped. The strength member 42 is connected to the annular ring 46 inthe junction member 38 and likewise lines 48 and 50 which are connectedto the casing have their strength members 52 and 54 respectivelyconnected to the ring 46. The conductors 56 and 58 of lines 48 and 50are connected to the coils 24 and 26 respectively. Any suitable switchmeans may be provided for controlling the flow of current through thecoils 28 on the source of power supply within the ship.

Since from the foregoing the construction and advantages of thisoverboard discharge chute are readily apparent, further description isbelieved to be unnecessary. However, since numerous modifications willreadily occur to those skilled in the art after a consideration of theforegoing. specification and accompanying drawings, it is not intendedto limit the invention to the precise embodiment shown and described,but all suitable modifications may 4 ing said casing towards the skin ofthe ship, said magnetic means including a U-shaped core having a pair ofsubstantially parallel legs and a central connecting portion, said legsextending through said casing, said central connecting portion overlyinga portion of the front wall of be readily resorted to which fall withinthe scope of theappended claims.
